Security is always a concern when you need to send sensitive files to the recipients on the outside. Secure Delivery is a convenient wizard which helps protect a set of files to be delivered with passwords or signatures sending them out via email. Both PDF and non-PDF files can be protected using secure delivery.

  1. Open a PDF and choose Security > Secure Delivery.

  2. In the Secure Delivery dialog box, go through the following four steps:

    • Select Envelope. Click to open the Envelope panel. Double-click the desired envelope or right-click and choose Apply to open it. You can use Add Text to add extra information onto the selected envelope.

    • Add Attachments. Click to add file attachments. In the dialog box, individually select one or multiple files and then click Open. All the selected files (both PDF files and non-PDF files) are displayed in the Attachments panel to the left in the envelope file. You can also attach a PDF portfolio that contains a collection of files.

    • Encrypt Files. Click to open the Security To apply the security scheme, directly click-drag an appropriate one to the document pane, or right-click and choose Apply Security Scheme. If there is no a security scheme yet that can be used, create one and apply it to the file.

    • Sign Document. Click to open the Sign/Certify panel, and select an appropriate signature scheme from Sign Document. Remember to save the document in order to apply the digital signature. If there is no a signature scheme yet, create one and then apply it to the file.

  1. Click Send when the document is ready. Your default email application opens with the envelope file attached to a new message that contains instructions of accessing the secured attachment. Then, fill in the required fields, such as recipients and subjects, and click Send.
